COMBINED COOKING-STOVE AND BAKING AND WARMING OVEN.

SPECIFICATION forming part of Letters Patent No. 333,714, dated January5,1886.

Application filed September 17, 1884. Serial No. 143,294. (No model.)

To all whom it may concern Be it known that I, FREDRIOK ARTMANN, ofLexington, in the county of Holmes and State of Mississippi, haveinvented new and useful Improvements in Combined Cooking-Stoves andBaking and \Varming Ovens, of which the followingisa full, clear, andexact description.

Reference is to be had to the accompanying drawings, forming part ofthis specificatiom'in which similarletters of reference indicatecorresponding parts in all the figures.

Fig. 4 is asectional end elevation of the same, taken through the line y Fig. 3.Fig. 5 is a sectional plan view of the same, taken through the line 2 2,Fig. 3.

The object of this invention is to provide u combined cooking-stoves andbaking and warming ovens constructed in such a manner as to economizefuel and make the said combined stoves and ovens more eli'ective andreliable than those constructed in the ordinary manner.

The invention consists in the construction and arrangement of parts, aswill be herein after fully described and claimed.

The outer end and back walls, A, may be made of iron or of bricks; butthe front plate, B,in which are formed the door-openings, and the topplate, 0, in which are formed the holes to receive boilers and othercooking-utensils, are made of iron.

D is the baking-oven, and E is the warming-oven, the walls of which areformed of fireclay slabs.

F is the fire-chamber, G is the fire-grate, and H is the ash-pit.

I is a damper,which is pivoted at the top of the inner side wall of thewarming-oven in such a position that when turned down it will close theentrance to the space between the ovens D E, and when turned up it willclose the space between the warming-oven E and the top plate, 0. Thespace between the top of the baking-oven D and the top plate, 0, isdivided int-o two fiues, J, by a longitudinal partition, K. The spacebetween the bakingovenD and the warming-oven E is divided into twofiues, L, by a vertical partition, M, which is widened toward its lowerend, as shown in Fig. 4 and by shade-lines in Figs. 3 and 5. The spacebelow thebakingoven D and the ash-pit H is divided into three parallelfines, N, by two partitions, O, extending from the wall of the tines Lfarthest from the fire-chamber F nearly to the end wall, A, at the outerside of the said firechamber, as shown in Fig. 7. The space between theouter wall of the warming-oven E and the end wall, A, is divided intotwo fiues, P, by a partitiomQ.

In the space or flue R beneath the warmingoven E, and directly oppositethe open end of the center flue N, is placed an angular guideplate, S,to divide the current of the heated products of combustion passing outof the said center flue N, spread the said products of combustionthrough the fiueR, and cause them to pass up through the fines I? in twonearly equal currents.

In the end walls, A, opposite the ends of the center flue N, are formedopenings closed by capplugs T U. The plugT extends inward in wedge form,as shown in Fig. 7, to guide the currents of the heated products ofcombustion from the side flues N into the center flue N, causing thesaid currents to meet at an acute angle, and preventing the saidcurrents from meeting in a direct line, being thrown into eddies, andimpeding the draft. With this construction, when the damper I is turneddown into the position shown in Fig. 3, the products of combustion fromthe fire-chamber F will pass through the fluesJ into the space or lineV, between the top of the warming-oven E and the top plate, 0, andthence into the flue \V,leading to the chimney.

When the damper I is turned up into the position shown in Fig. 5, theproducts of combustion from the firechamber F will pass through the twotlues J, will be deflected downward by the damper I, will pass throughthe diving-fines L into the side fines N, will pass through the centerflue N into the flue R, will pass up through the fines Pinto the flue V,and will pass thence into the line W,

leading to the chimney. By this arrangement the products of combustionin their passage through the various flues will thoroughly heat the ovenD, so as to bake bread or other substances, and will warm the oven E, soas to keep hot whatever may be placed in it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

' 1. The combination, with the stove, of the three flues N below theoven thereof, and the removable wedge-shaped plug T in the end plate, infront of the central flue N, whereby the lines may be cleaned byremoving said plug and the products of combustion be made
